Theresa May could find a backlash from pensioners here pictured with Donald Tusk
Her remarks could embarrass Theresa May who is likely to come under pressure from taxpayers over the subject after the Prime Minister waded into the debate.
More than five million women and men have had their pensions cut as a result of new laws introduced under EU legislation.
The adoption of Council Directive 79/7/EEC, which addresses equal treatment in relation to statutory social security matters was introduced at the end of 1984.
David Cameron left the country in a complete mess
Changes to the taxpayer funded pension were introduced in the United Kingdom in 1995 and updated by a variety of governments over the years.
In 2007, Tony Blair and Gordon Brown raised the pension age for women to 65 by 2020 which led to the massive cuts for 2.6 million.
They also increased the equal state pension age from 66 to 68, to be brought in between 2024 and 2046.
David Cameron expedited the pensions issue angering many older poorer people
In 2011 the timetable was sped up by Cameron which meant state pension ages would be equal at 65 by 2018, and rise to 66 for everyone by 2020.
The new changes currently affect around five million people born between 1953 and 1960 in Great Britain accounting for as much as £42,000 each.
This is despite the fact that many millions of these people worked and paid into the system from the age of just 16.
On February 1, the Prime Minister acknowledged the pension crisis engulfing Britain.
Mrs May said: “We did commit over £1billion to lessen the impact on those worst affected so no-one will see their pension age change by more than 18 months.
"But there is a wider point here, we do have to be realistic in looking at pension ages about the fact that people are living longer.”
